Abstract
An optical analysis device includes a light source, a beam shaping unit, a relative movement unit, a photodetector, and a position detector. The light source unit generates a light beam. The beam shaping unit forms a flat beam portion. The relative movement unit is configured to cause the flat beam portion and a test sample including marker particles to relatively move in a minor axis direction of the flat beam portion. The photodetector is configured to detect a light intensity and a light emitting position in a plane orthogonal to the minor axis direction. The position detector is capable of detecting spatial positions of the marker particles on the basis of information on a relative movement amount of the flat beam portion, information on the light intensity and the light emitting position, and a change of the light intensity generated according to a relative movement of the flat beam portion.
